From “Material Instability” To “Process Control” ----------A Real Case of How DSM Helped A Blade Manufacturer Optimize Its Supply Chain

In the industrial blade industry, we often hear the same concern from manufacturers:

“Our problem isn’t that we can’t make good blades — it’s that we can’t make them consistently.”

This is not an isolated issue. It’s a common challenge across the industry.

Today, we’d like to share a real customer case to illustrate how these problems can be identified — and solved.

1. Customer Background

The client is a mid-sized industrial blade manufacturer, producing:

• Food processing blades

• Packaging and slitting blades

• Selected medical cutting tools

Their annual stainless steel consumption reaches approximately tens of thousands of tons.

Before working with DSM, they already had established suppliers — but were facing persistent issues.

2. Key Challenges Faced by the Customer

2.1 Inconsistent Material Performance

Using the same grade (e.g., 5Cr15MoV / 1.4116):

• Some batches performed well

• Others wore out quickly

This led to:

• Unstable process parameters

• Frequent machine adjustments

2.2 Slitting Quality Affecting Production

Their previous workflow:

Steel mill → Third-party slitting → In-house processing

Issues included:

• Excessive edge burrs damaging tooling

• Inconsistent width tolerances

• Additional edge finishing required

Result:

• Increased cost

• Reduced production efficiency

2.3 Unstable Heat Treatment Results

With identical heat treatment processes:

• Some batches met hardness targets

• Others showed significant deviations

Leading to:

• Inconsistent blade lifespan

• Increased customer complaints

2.4 Unreliable Supply

During market fluctuations:

• Existing suppliers failed to deliver consistently

• Production schedules were disrupted

Direct impact:

• Delayed deliveries to end customers

3. How DSM Stepped In

Instead of simply supplying material, DSM took a different approach:

Start from the application and redesign the material solution.

Step 1: Material Re-evaluation Based on Application

We analyzed their product mix:

• Food processing blades → prioritize corrosion resistance and stability

• Slitting blades → emphasize wear resistance and dimensional precision

Rather than relying on a single grade, we optimized the material combination.

Step 2: Supplying Pre-Processed Materials

DSM provided:

• Precision slitting (down to narrow widths)

• Tight tolerance control

• Low-burr edge quality

Result:

• Materials could go directly into production

• One external processing step eliminated

• Reduced cumulative errors

Step 3: Stabilizing Heat Treatment Outcomes (Key Factor)

Many issues did not originate from heat treatment itself, but from:

the condition of the raw material

DSM improved this by:

• Controlled spheroidizing annealing

• Optimized microstructure uniformity

• Strict batch consistency management

Outcome:

• More predictable hardness results

• Improved process stability

Step 4: Building a Reliable Supply System

With:

• Stable upstream mill resources

• Multi-location inventory and processing centers

DSM ensured:

• Continuous supply

• Fast response capability

4. Results Achieved

After 3–6 months of cooperation, the improvements were clear:

✔ More Stable Production

• Fewer machine adjustments

• Higher level of process standardization

✔ Improved Blade Consistency

• Reduced batch-to-batch variation

• Fewer customer complaints

✔ Lower Overall Cost

Although DSM was not the lowest-priced supplier:

Total cost decreased due to:

• Less outsourcing

• Lower scrap rates

• Higher efficiency

✔ More Reliable Supply Chain

• No more supply disruptions

• Better delivery reliability

5. The Real Change Behind This Case

The key transformation was not:

❌ Switching to a different steel grade

But rather:

✔ Upgrading from “buying material” to “optimizing the entire material supply chain”

6. What DSM Offers to Blade Manufacturers

DSM provides more than just stainless steel:

1. Stable Material Supply

Ensuring consistency batch after batch

2. Integrated Processing Services

• Slitting

• Cut-to-length / shearing

• Ultra-thin rolling

3. Upstream Heat Treatment Control

Helping customers achieve more stable results

4. Application-Oriented Material Selection

Not the most expensive — but the most suitable

Conclusion

In the industrial blade industry:

The real competition is not just about blade performance — but about supply chain stability.

If your factory is facing:

• Inconsistent material performance

• Difficulty standardizing processes

• Limited production efficiency

Then the issue may not lie in your equipment or techniques,

but in:

whether you have a supplier who truly understands your application.

If you are experiencing similar challenges with material consistency, processing efficiency, or supply stability, DSM is here to help.
